IMPROVEMENT IN VEHlCLE-WH EELS.

Specification forming part of Letters Patent No. 195,875, dated October2, 1877; application filed September 5, 1877.

To all whom it may concern:

Be it known that I, WALTER J. Dnnw, of Grand Rapids, Kent county,Michigan, have invented certainnew and useful Improvements inVehicle-Wheels; and I do hereby declare the following to be a full,clear, and exact description of the same.

My invention relates particularly to wheels and axles for vehicles,though it is equally applicable for street and railroad cars; and itconsists in providing the hub with a hollou rim having a sand band orprojection on its iimer side, and a stationary chair or box providedwith a griddle or projection where it enters the hub, to holdfriction-wheels to their place, and keys at; the other end of the chairto hold the axle, all as hereinafter more fully set forth. ,v

In the annexed drawing, to which reference is made, and which fullyillustrates my invention, Figure 1 is a longitudinal section of myinvention. 'Fig. 2 is 'a side view of the .wheel. are enlarged detailedviews of the keys.

A represents the hub of a wagon-wheel, provided with an independentaxle, B, secured therein. This axle projects through the center of p ametal chair or box, (3, the bore of whichis larger than the axle, so asnot to allowit to touch,'but. to bring the weight of the load upon thefriction-wheels ca. These wheels are placed within the rim D of thehollow metal 3 hub A, and travel aroundon the inside of the hub as thewheel revolves, and consequently reduce the friction, as it makes arolling bearing. One side of the wheels so travels around on the box orchair 0, which projects into the rim of the hub, and is just largeenough to fill up the va cant place after the rollers have been placedtherein, and the other side travels around on the inside of the rim D ofthe hub, as above stated.

The axle B has a bearing at the inner end, or, in other words, it ismade to fit the inner end of the box, where it is held in place by meansof two keys, G G, entering a groove or neck, as, in the axle, and heldin place by bolts 1). The rim D is on its side provided or formed with asand-band, D, to hold the wheels in the rim, and the chair or box 0 isformed with a collar or griddle, d, which enters into said sand-band,and excludes all dust and dirt.

The box or chair is fastened to the body of an ordinary wagon by boltsand gripes in such a manner as to make it perfectly rigid. At the rearend of the wagon it is placed andfastened between the bolster andaxle-tree, and at the front end between the wooden axle-tree andsand-board.

For streetcars or railroad-cars the axle projects from one wheel to theother on the oppo site side.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isi A wheel-hub,A,provided with ahollow rim, D, having a sand-band, D, in combination with the axle B,friction-wheels a, stationary chair or box 0, and keys Gr, allconstructed substantially as and for the purposes herein set forth.
